3. edit line 184 of linux2.6/Makefile to point to your cross compiler (or comment it out if you know the varaible is set elsewhere).

4. edit include/asm/mach-types.h (the number has changed to 2028 - but the boot loader only knows about 1235)

(you may need to 'make' once and ctrl-c to get the mach-types file generated the first time.)

//define MACH_TYPE_ZIR2412 1235

define MACH_TYPE_DIDJ 1235

...

//define MACH_TYPE_DIDJ 2028

4.1 instead of editig mach-types.h you can edit the file that it is generated from, mach-types (no.h!)
in /linux-2.6/arch/arm/tools, edit the file and look for 2028, copy everything on the line upto 2028:

didj MACH_DIDJ DIDJ

comment out the 2028 line and now search for 1235 and replace the line with the above, make sure you add 1235 to the end:

didj MACH_DIDJ DIDJ 1235

This allows you to do 'make clean' without having to re-edit mach-types.h each time, if you also own an explorer you might not want to do this.
